GAUGE.

Application .filed December 12, 1925. Serial No. 75,108.

The object of my invention is to provide a gauge of the dial indicator type which will be gearless and which will also be very simple in construction, positive and accurate in operation and capable of withstanding the hard usage to which gauges of this type are commonly subjected.

A further object of my invention is to provide certain improvements in the construction, form and arrangement of the several parts whereby the working parts of the gauge are wholly supported by a separable casing back, for facilitating the removal of the parts for inspection and replacement, said casing back also being provided with an integral depending hollow lug tor slidably mounting the gauge plunger and with integral stops for limiting the inward and out ward movements of the plunger.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Fig. 1 represents the gauge in front elevation.

Fig. 2 represents a horizontal section taken in the plane of the line II II of Fig. 1.

Fig. 3 represents a transverse vertical section taken in the plane of the line III-III of Fig. 4, r

Fig. 4: represents a vertical longitudinal section taken in the planes of the line IV IV of Fig. 3.

Fig. 5 represents a detail section showing the rock lever and plunger in full. lines in their normal position and in dotted lines in the positions tllBYflSSUDJG when the plunger has been moved to the limit of its inward movement.

The separable back 1 of the casing is provided with an integral ear 2 for attaching the gauge to a suitable standard. This cas ing back is also provided with an integral casing back 1 being arranged in position to act as the stop for engaging the inner end of i 1 1 as the plunger is moved inwardly.

ing back 1 and at its front end in a front lat' eral branch 9 of a bracket 10, the back lateral branch 11 of which is secured to the easing back 1. This bracket has an elongated slot 12 extending parallel to the hand arbor 8. V

The hand arbor 8'is provided with an enlarged cylindrical portion between its ends, which cylindrical portion has a spiral groove 13 along the same.

A rod 14 is spaced from and arranged parallel to the hand arbor 8, which rod is supported at its rear end in the casing back 1 and at its front end in the front lateral branch 9 of the bracket 10. This rod forms a support for a slidable sleeve 15 which is provided with oppositely arranged projections 16 and 17. the projection 16 being located within the spiral groove 13 of the hand arbor and the projection 17 being located in the elongated groove 12 of the bracket 10, to prevent the sleeve from turning as it is moved along the rod 14 to rotate the hand arbor.

A rock lever is pivoted at 18 in a forward ly projecting branch 19 of the bracket 20, secured to the casing back 1 the short arm 21 of which lever is engaged by the inner end of the plunger 4 and the long arm 22 of? which lever engages the back of the slidablc sleeve 15, to move it forwardly along the rod This long arm 22 is preferably bifurcated so that the free ends of its branches will press equally against the back of the sleeve upon opposite sides of the rod 1 1 to prevent any tendency of the sleeve to cramp or bind on the rod.

A spring 23 is secured at 24 to the from end of the bracket branch 19, the free end of which spring engages the front of the slidable sleeve 15 to reverse its movement and thereby return the parts to their normal position when the plunger 4: is released.

The back 1 is shown as removably secured around its periphery to the cylindrical side "all oi the casing by screws 26.

From the above description it will be seen no i that a very simple mechanism is provided for operatively connecting the hand of the gauge to the plunger. It will also be seen that all of the working parts are carried by the separable casing back, the supports for the parts at the same time being made very strong and durable.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention; hence, I do not intend to be limited to the particular embodiment herein shown and described, but

What I claim is 1. In a gauge of the dial indicator type, a hand arbor having a spiral groove, a plunger and an operating connection between the plunger and arbor comprising a suitable sup-- port, a sleeve slidable along the same parallel to the arbor and engaging said spiral groove, means for preventing the sleeve from turning, a rock lever having a short arm engaged by said plunger and a long arm engaging said sleeve, and a spring for returning the parts to their normal positions.

2. In a gauge of the dial indicator type, a hand arbor having a spiral groove, a plunger movable in a straight line at right angles to said arbor and an operating connection between the plunger and arbor comprising a. suitable support, a sleeve slidable along the same parallel to the arbor and engaging said spiral groove, means for preventing the sleeve from turning, a rock lever having a short arm engaged by said plunger and a long arm engaging said sleeve, and a spring for returning the parts to their normal positions.

3.
